Answer 1

My hens yolks darken when they get more protein. In the winter they get yellower but if I give them a handful of meal worms each day by the following week they’ll darken up again.

You can also add specific foods to their diet that will change yolk color.

For me the quality is less about the color and more about the texture. A good solid shell, a yolk that stands up and egg white that doesn’t run like water.
